A method of monitoring the fluid pressure of, with a sensor of a tire pressure management system disposed without, a tire that prevents overinflation of same. The method of monitoring a fluid pressure of a tire with a sensor, disposed in conduit assemblies for conducting fluid to or from the tire, of a tire pressure management system includes providing a pulse of compressed fluid to the conduit assemblies, unless a counter exceeds a count, the fluid in the conduit assemblies thereafter having a conduit pressure. The pulse has a duration that corresponds to a ratio defined by a first predetermined amount divided by a second predetermined amount.

Tire pressure monitoring method

The crop lifter and air assist feeding assembly for a floating cutter bar header includes a lower tube that is generally horizontal. An upper tube is fixed to the front end of the horizontal tube and extends upwardly and rearwardly to an air discharge orifice. A vine lifting rod is attached to the upper tube. The lower tube is mounted under a knife guard. A skid plate connected to the cutter bar has an attached terminal air supply tube. The terminal air supply tube passes through a front portion of the skid plate and attaches to the lower tube. An elastic and flexible tube is positioned above the skid plate, and is connected to the terminal supply tube and to terminal air supply tube and a blower air delivery tube under the skid plate.

Grain harvester header with air assist

A method of verifying the integrity of a valve in service in a tire pressure management system is disclosed. The method of verifying valve integrity of a valve interposed between a tire and conduit assemblies for conducting fluid to and/or from the tire in a tire maintenance system includes closing the valve for prohibiting fluid flow into the conduit assemblies in fluid communication with the valve and monitoring the pressure of fluid in the conduit assemblies in fluid communication with the valve for ascertaining a pressure increase therein.

Tire pressure management system valve integrity verification method

A tire inflation method is disclosed for moving air through a fluid control circuit to at least one tire that is below a target pressure. The dynamic pressure of the moving air in the fluid control circuit is monitored. A pressure control valve in the fluid control circuit is cycled on and off to prevent the dynamic pressure from reaching a predetermined amount over the target pressure.

Tire inflation method

A tire inflation system and wheel speed sensor system having a hollow shaft rotatable with a drive mechanism. The shaft extends into the hollow end of an axle. A angular velocity system rotates with the shaft within the hollow end of the axle. A sensor, mounted within the axle, senses the rotation of the angular velocity system. The hollow shaft is a conduit for air from an air source to at least one tire.

Tire inflation system and wheel sensor and method of use

A combined tire inflation system and a wheel speed sensor for a vehicle steer axle has a steerable spindle with a substantially hollow interior portion. A shaft, located in the hollow interior portion, connects a rotatable hub cap adjacent the spindle and a sensor at least partially within the spindle. A magnet is secured to the shaft and rotates with the shaft. A sensor is mounted adjacent the magnet for sensing the rotation of the magnet. The shaft has a hollow interior that connects an air source with a tire associated with the hub cap.

Vehicle tire inflation system and sensor and method of use

A method of inflating a tire, or vehicle tire, that minimizes the amount of time needed for same is disclosed. The method of inflating a tire with a tire pressure management system includes introducing continuous fluid flow of a fluid into the tire, ascertaining the dynamic pressure of the fluid during said introducing continuous fluid flow, terminating continuous fluid flow when the dynamic pressure exceeds or equals a predetermined amount, and introducing pulsed fluid flow of the fluid into the tire.

A method for control of a tire pressure management system (or central tire inflation system) is provided which enables active adaptation of control variables in the system in response to variations in air line volume. The air line volume in a conduit between an air source and a vehicle tire is determined. Subsequently, one or more values for control variables are adjusted in response to the air line volume and various parameters associated with the system are determined in response to the adjusted values of the control variables.
